America was still reeling from a spate of pretend assassinations last week when it was shaken by an attempted real one. First, comedian Kathy Griffin was summarily run through the internet's shame machine for posing with a fake severed president head. Then corporate sponsors pulled their support of a Shakespeare in the Park production of Julius Cæsarfeaturing a Trumpish tyrant getting the traditional pincushioning. Trump supporters reacted to these depictions of assassination — one comedic, one dramatic — in much the same way that their arch-enemies, radical Muslims, have to cartoon or operatic depictions of The Prophet — with censorious outrage. At least the imbroglio served to introduce them to the works of Shakespeare.

After James Hodgkinson attempted to assassinate members of the Republican congressional baseball team, a lot of conservatives hopped up and down pointing their fingers at those reckless liberal polemicists. Newt Gingrich, ever our national peacemaker and voice of moderation, decried the climate of increasing hostility on the left that could lead to an attempt on the lives of GOP lawmakers from an outspoken Trump opponent.

Allow me to dissent.

Sorry to add insult to imaginary injury, but, as a former political cartoonist who once drew Ronald Reagan's head impaled on a bamboo pole, I hold with the unfashionable notion that artists should be allowed to do whatever they want: that Lionel Shriver should be allowed to write about Latinos, that Dana Schutz should be allowed to paint Emmett Till, and that Kathy Griffin should be allowed to accessorize with the president's head.

Of course "allowed to" doesn't necessarily mean "universally praised and lavishly rewarded for." An artist's job is to take risks, and taking risks means sometimes doing things that turn out to be stupid and wrong. The riskier the subject matter, the better or funnier your art had better be. If you fail, people are going to be offended and mad and call you names on the internet. They will also do this if you succeed. If your intention is to provoke, you don't apologize when you succeed; the correct response, when you waggle a severed president's head at the public and the public is outraged, is: "That's right, and here's Mitch McConnell's, too."

Americans who take their kids to Saw and Alien movies still seem oddly shocked by violent imagery in political satire, maybe because most mainstream American editorial cartoonists have turned in such lazy, gutless, Donkeys-&-Elephants hackwork for the last half-century or so. Their British counterparts have always been crueler and funnier — possibly because they have a history of literal, rather than symbolic, beheadings in managing transitions of power. Crude images of sex and violence, gluttony and flatulence, dismemberment and cannibalism recur in the cartoons of Gillray and Cruikshank, and persist in the work of their successors, like Ralph Steadman, who drew Nixon as a malignancy being excised from the heart of the Republic, and Steve Bell, who draws President Trump's head as a toilet.

These obscene, scatological, and violent images have the obvious virtue of shock; you don't give them a glance and chuckle and then turn to the Style section. But they also serve as pointed visual metaphors, telling impolitic truths about politics: that it is, beneath all its pompous rhetoric, a brutal business of eating and rutting and killing, of consumption, resources, reproduction and waste, rapine and slaughter, of pushing people around and telling them what to do, of protecting what's yours or, more often, taking what's not.

The inequality between classes in this country has been getting wider and more institutional, more shameless and insulting, for decades. The aristocracy gets everything from cushier seats on airlines to a cushier legal system. Large swaths of the populace have been deemed economically unnecessary, and they are humiliated, frightened, angry, and desperate. Meanwhile the government has grown ever feebler and more sclerotic, unable even to credibly pretend it isn't wholly owned and controlled by the wealthy. The venerable American tradition of blasé contempt for the government has lately become a more passionate, personal loathing. Congressmen have been insulating themselves from their constituents for fear of the vituperation they'll meet. With Congress' current effort to revoke millions of Americans' health care, a lot of people feel as if their elected representatives are literally threatening their and their families' lives. It should maybe not come as an incomprehensible shock that some of them are threatening back.

These sorts of vast systemic inequities have historically had a way of correcting themselves, either through internal reforms or else by a lot of people getting dragged out of bed and garroted. Our system has so far proved impressively resistant to attempts at reform.

Both conservatives and liberals like to rile themselves up to the point of hysteria like kids on a sleepover with visions of imminent dystopia, either socialist or fascist, depending on their ideological boogeymen. But maybe this increasingly violent imagery in our culture speaks of something larger and more ominous than the obvious partisan rancor. Both those controversial artistic assassinations— the guillotine and Cæsar's stabbing — were archaic allusions, and therefore explicitly symbolic, in the way that terms like "cruficixion" and "witch hunt" are. But last week we were reminded that symbolic violence is not actually the worst kind. It is, in fact, a healthy sign of a society still at least somewhat successfully sublimating its aggression. A free press is society's equivalent of a conscience; its art is its dreams, and satire its jokes, telling taboo truths, expressing repressed wishes.

You quash or ignore such portents at your peril. To paraphrase violent provocateur Patrick Henry, "Cæsar had his Brutus; Charles I had his Cromwell, and Donald Trump — may profit by their example."
